I believe they did it because.

1) You don't have to check it, therefore takes away all accountability (Someone to stand up and say it is wrong, better luck next time!)
2) Help vendors (that invest in the NHRA) sell products.
3) 1 less person to pay to work the races/teardown. They could get less experieneced. cheaper labor to do the job.
4) Speed up teardowns.

It just goes to show as soon as they legalize a go fast replacement part it opens up the next door, and then the next door. Legalize open spring pressure, then you find the next weekness (lifter, cam material) then you fix that and so on. Results, better products, more Hp, Lower ET's, Higher MPH, MUCH HIGHER PRICE TAG TO KEEP UP, Lower participation (Due to price tag), Higher HP factors (Due to the newly found performance). Stocker engines being priced sky high. The list goes on. Does anyone notice that in time past when money was tight, like it is now, there were allot of cars running. More participation? The reason that I see is people like rules, as long as they are the same for everyone. You used to spend your time working through your combo (testing). Now allot of people "checkbook race".
